I've been thinking about that. It would certainly be within the legal 
definition of a database to call a PNG file a database. This would mean 
that the producer of a map tile has a choice - either declare your map 
tile to be ODbL, lose the ability to license your map tile differently, 
but not have to share any databases behind it; or choose to declare your 
map tile a produced work that you can license in a different way but 
then you have to share the database behind it.

Our community norm currently says it is a database if it was intended to 
extract the data... some time in the past someone said "it is a database 
if you say it is one". Maybe that wasn't so bad after all.

Bye
Frederik
